Other-than-temporary impairment losses on investments held in nuclear decommissioning trust funds recognized in earnings for Virginia Power were not material for the three and nine months ended September 30, 2018 and 2017. Equity Method Investments Dominion Energy Blue Racer In October 2018, Dominion Energy entered into an agreement to sell its 50% limited partnership interest in Blue Racer. The transaction is expected to close in the fourth quarter of 2018, subject to clearance from the Federal Trade Commission under the Hart-Scott-Rodino Act and the satisfaction of customary closing conditions, for up-front cash consideration of $1.05 billion. As a result, Dominion Energy expects to recognize a gain of approximately $380 million ($230 million after-tax) in the fourth quarter of 2018. In addition, the agreement contains additional deferred consideration of $150 million, subject to increase for interest costs effective March 2019, payable upon the purchaser’s availability of cash. This will result in a gain when realizable. Also, the purchaser agreed to pay additional consideration contingent upon the achievement of certain financial performance milestones of Blue Racer from 2019 through 2021. Pursuant to the purchase agreement, the aggregate will not exceed $300 million, which represents a gain contingency, and, as a result, Dominion Energy will not recognize any additional gain unless such consideration is realizable. Atlantic Coast Pipeline Dominion Energy recorded contributions of $147 million and $84 million during the three months ended September 30, 2018 and 2017, respectively, and $306 million and $286 million during the nine months ended September 30, 2018 and 2017, respectively, to Atlantic Coast Pipeline. At September 30, 2018, Dominion Energy had $37 million of contributions payable to Atlantic Coast Pipeline included within other current liabilities in the Consolidated Balance Sheets. DETI provides services to Atlantic Coast Pipeline which totaled $50 million and $32 million for the three months ended September 30, 2018 and 2017, respectively, and $156 million and $93 million for the nine months ended September 30, 2018 and 2017, respectively, included in operating revenue in Dominion Energy and Dominion Energy Gas’ Consolidated Statements of Income. Amounts receivable related to these services were $15 million and $12 million at September 30, 2018 and December 31, 2017, respectively, composed entirely of accrued unbilled revenue, included in other receivables in Dominion Energy and Dominion Energy Gas’ Consolidated Balance Sheets. In October 2017, Dominion Energy entered into a guarantee agreement to support a portion of Atlantic Coast Pipeline’s obligation under its credit facility. See Note 16 for more information. NedPower At December 31, 2017, Dominion Energy had a liability of $17 million recorded to other deferred credits and other liabilities on the Consolidated Balance Sheets relating to its commitment to provide further financial support for NedPower. At September 30, 2018, Dominion Energy had no remaining liability. Other – Catalyst Old River Hydroelectric Limited Partnership In September 2018, Dominion Energy completed the sale of its 25% limited partnership interest in Catalyst Old River Hydroelectric Limited Partnership and received proceeds of $91 million. The sale resulted in a gain of $87 million ($63 million after-tax), which is included in other income in Dominion Energy’s Consolidated Statement of Income. Dominion Energy Gas Iroquois Dominion Energy Gas’ equity earnings totaled $18 million and $15 million for the nine months ended September 30, 2018 and 2017, respectively. Dominion Energy Gas received distributions of $20 million and $17 million for the nine months ended September 30, 2018 and 2017, respectively. At September 30, 2018 and December 31, 2017, the carrying amount of Dominion Energy Gas’ investment of $93 million and $95 million, respectively exceeded its share of underlying equity in net assets by $8 million. The difference reflects equity method goodwill and is not being amortized.
